Application filed December 12, 1912. Serial No. 736,324.

To (/77 ar/mm v'f' nmy concern:

lie it known that l, Jnssin L. Jonas, a citizen of the United States,and a resident of lvlaricopa, in the county of Kern and State ofCalifornia, have invented an improvement in Cans, of which the followingis a specification.

My invention is an improvement in cans, and has for its object theprovision of mechanism in connection with a can of the character whereinresiliency is required in the bottom of the can, as for instance in oilcans and the like, wherein mechanism is provided within the can forinsuring that the bottom of the can will always possess sufficientresiliency to insure the springing back or outward of the bottom afterit has been depressed and the pressure has been relaxed.

In the drawings, Figure 1 is a side view of an oil can provided with theimprovement, the bottom of the can being in section, and Fig. 2 is asection on the line 2-9 of Fig. 1.

In the embodiment of the invention shown in the drawings, the can is anordinary oil can consisting of a body 1 having its lower edge flangedoutwardly, as indicated at 2, and the bottom 3 in the shape of a disk ofsomewhat greater size than the bottom of the body, and the free edge ofthe bottom is turned over upon the flange 2, as indicated at l, to lockthe bottom in place on the body. The body may be of any desired shape,either approximately conical, as shown, or cylindrical, and in eithercase, a nipple 5 provided at the top of the body into which is threadedthe delivery spout ,(i.

.l'n the type of oil can shown, the oil is ejected by alternatelypressing and relaxing the bottom 3, holding the can between the fingers,with the thumb pressing the bottom. In this manner a jet of oil isthrown from the spout 6 at every depression of the thumb, and air isdrawn into the can to replace the oil ejected when the bottom springsbackward to its original position. After continued use with this type ofcan, the bottom loses its resiliency and inclines to cup or archinwardly, so that it is impossible to eject the oil in the manner abovedescribed. 'The present invention is designed to obviate this trouble,by insuring that the bottom will always be resilient enough to return toits original position.

A strip 7 of metal of suitable width and length is arranged transverselyof the can within the same, the ends 8 of the strip bcing receivedbetween the bottom 3 and the flange 9 of the body, in such manner thatwhen the edge of the bottom is bent down upon the flange :2, as shown at-11, the ends of the strip will be locked in place between the bottomand the flange.

hips 9 and 10 are arranged coaxially with each other, one of the cups 1)being secured to the central portion of the strip 7 by means of a rivet11, while the other cup 10 is socured to the bottom at the centerthereof by means of a rivet 12.

The free edges of the cups are spaced apart slightly, as indicated at13, so that the said cups may move toward each other a limited distancewithout engaging with each other.

A coil spring 1 1 of suitable strength is arranged within the cups, eachend of the spring being seated in one of the cups in such manner thatthe spring is held in place by the cups. The strength of the spring, asalso the size of the strip 7, will depend to some evtenl upon the sizeof the oil can and also upon the weight of the bottom 3. It will beevident that with heavy cans made of heavy material, a heavy spring letwill be necessary, while with lighter cans made of lighter material, aweaker spring may be used. in any event, the spring tends to force thebottom 3 away from the body of the strip 7.

in operation with the improved can, when pressure is exerted upon thebottom at the center thereof, the said bottom will be depressed,eompressing the spring 1-41; between the cups 9 and 10. As soon as thepressure is relaxed, the spring will expand and will force the bottomoutwardly to its original position.

l t will be evident that the bottom of a can provided with thein'iprovcment will retain its resiliency indefinitely, so that the canmay be used until it is completely worn out.

It will be evident that the strip and the cups may be secured in placein any other manner than that shown, if so desired.

I claim 1,. In a can comprising a body and a re silientbottom secured tothe lower end of the body, a strip of metal. arranged t'ansverscly ofthe bottom within the can, the central portion of the strip being spacedapart from the inner surface of the bottom and the ends of the stripbeing secured to the can between the bottom and the body, a pair ofoppositely arranged cups arranged coaxially of the can, one of the cupshaving its bottom secured to the center of the strip and the otherhaving its bottom secured to the center of the bottom of the can, and acoil spring having its ends seated in the cups and normally pressing thebottom away from the strip.

2. In a can comprising a body and a re silient bottom secured to thelower end of the body, a strip of metal arranged transversely of thebottom within the can, the

central portion of the strip being spaced apart from the inner surfaceof the bot-tom and the ends of the strip being secured to the canbetween the bottom and the body, a coil spring arranged between thebottom and the center of the strip, and means secured to the strip andto the bottom of the can for engaging the end of the spring to hold thespring in place.
